FABRIC-TURFING IMPLEM ENT.

SPECIFICATION forming part of Letters Patent No. 409,139, dated August13, 1889. Application filed August 16, 1888. Serial No. 282,843. (Nomodel.)

To all whom it may concern,.-

Be it known that I, MARTIN L. CONNETT, a citizen of the United States,residing at Bellefontaine, in the county of Logan and State of Ohio,have invented a new and useful Improvement in Fabric-Turfing Implements,of which the following is a specification.

My invention relates to improvements in fabric-turiing implements inwhich a reciprocating threaded needle is operated to puncture the fabricin its downward or forward movement, carrying with it the thread, and inits backward or upward movement withdrawing only a part of the thread toproduce a loop of the latter on the rear or under side of the fabric;and the objects of ,my improvements are, first, to provide anautomaticallyoperative lock to stop the feed of the thread in theupstroke of the needle, and thereby avoid the use and disadvantages ofthe tension mechanism, impingers, or plungers commonly employed in suchdevices to control the feed of the thread; second, to produce a turflngimplement in which the needle employed may be an ordinary sewing-machineneedle of any desired degree of iineness third, to produce a turiingimplement of comparatively few parts which shall be compact in form,durable and reliable, and convenient in its operation.

My invention consists in the general construction of my improved device;and it further consists in details of construction and combinations ofparts.

In the drawings, Figures l, 2, 3, and et are views in side elevation ofmy improved device, illustrating the relative positions of parts duringdifferent stages of the operation; Fig. 5, a similar view, partlysectional, showing the internal construction; Fig. 6, a perspective viewof a detail; Fig. 7, a similar View of the whole device, except thedetails shown in Figs. 6 and 8, with parts detached; and Fig. 8, asimilar view of a detail.

C is a holder in the form of a sheath, and E a presser-foot formed,preferably, from a single length of stiff Wire, and fastened at itsopposite ends upon the back of the sheath.

B is a needle-bar open on one side and longer than the sheath @,in whichit is adapted to be reciprocated. Toward one end the needle-bar isprovided in its lateral edges with corresponding notches t adjacent toits open or forward side, and toward the opposite end it is cut away onits rear side to afford a recess for a block G. Adjacent to the recessthe extremity of the rear side of the needlebar is flanged 'outward toproduce the stop I, which limits the upward movement of the needle-barby striking against the end y of the sheath, as hereinafter described.

The block G is pivotally secured in the needle-bar by a pin s, whichpasses through a perforation s in the block and rests at opposite endsin bearings S2 in the needle-bar. The rear side of the block G is cutaway and beveled, as shown, toward its upper extremity, which extendsabove the recess and stop I, so that as the block rests against the rearside of the needle-bar, which it does normally, as hereinafterdescribed, its position is slightly oblique with reference to theneedle-bar.

On its forward side the block G is provided with a narrow extension orlug G', which is recessed on its under side to afford an oblique slot p.A needle-socket q extends from the bottom of the block toward the upperextremity of the latter, and a clamp-screw H, for clamping the needle,enters the socket from the rear of the block G. An eye-0 extends from apoint adjacent to the socket q at the bottom of the block diagonallythrough the latter and lug G', crossing' the slot p near the innerextremity of the latter.

K is a stirrup, comprising a strip of springwire doubled to render twoparallel lengths, which are curved, as shown at and secured. at theirfree ends in a knob or handle A. The stirrup K is within the needle-bar,with its knob at the top of the latter and its loop end K engaging theoblique slot p in the lug G.

The reciprocation of the needle-bar in its sheath is produced bypressure upon the knob to cause it to bear against the upper extremityof the needle-bar and force the latter down, and raising the knob tocause the loop end K of the stirrup to engage the inner end of the slotp and draw the needle-bar up. The length of -the stirrup is slightly inexcess of the distance from the upper cxtremityof the needleba'r to theinner end of the slot. j), whereby the end K has limited play in theslot across the path of the eye o and operates as a lock to control thefeed of a thread, as hereinafter described.

'lhe curves a; in the stirrup permit the latter to rest against oppositesides of its casing, which causes the stirrup toward its loop end tooperate as a spring and bear against the face of the block G to retainthe latter normally against the rear side of the needle-bar, as beforedescribed.

D is a flat curved friction-spring, which extends longitudinally of theneedle-bar between the open side of the latter and the sheath. Thespring l) is bent and doubled over toward one end to produce a headcomprising lateral proj ectious on opposite sides, which afford,respectbrely, a catch t, to engage the notches t, before referred to, inthe needle-bar, and a stop D. Of course the head may be formed in anyother convenient way. The engagement of the catch t with a pair ofnotches t causes the spring D to travel with the needle-bar as itreciprocates and produce increased frictional contact between the latterand the sheath to overcome the tendency of the needle-bar to descend byits own weight without pressure upon the knob, and to permit initiallowering of the stirrup to unlock the thread, as hereinafter described.ln the downward plunge of the needle-bar the stop D strikes against theupper edge yy of the sheath, and it may be adjusted to shorten orlengthen the plunge by engaging the catch t with notches 1f of differentheights.

The operation is as follows: A needle F, having an eye toward its point,is adjusted in the needle-socket q and secured by means of theclamp-screw ll. Then thus adjusted, the needle extends normallyobliquely forward, owing to the angle at which the block G is held bythe spring-stirrup, as before described. A slight backward pressureagainst the needle will cause it and the pivotal block G to turn to aposition in line with the needle-bar, as shown by dotted lines in Fig.i, from which when released it will spring to its normally-obliqueposition. A thread J of the material desired to produce the turf ispassed through the eye o from the upper side of the lug G', crossing theslot p between the inner extremity of the latter and the end K of thestirrup. The end of the threa'd is then passed through the eye of theneedle. The oblique position of the needle causes it in its downwardplunge to enter the fabric at an angle, and as it descends draw thedevice forward a certain distance governed by the angle of itsinclination and the extent of the plunge below the presser-foot. Theneedle is prevented from yielding in a forward direction by theimpingement of the upper part of the block against the rear of theneedlebar, as before described. As the needle is raised, however, thepressure of its forward side against the fabric causes the needle tovibrate backward and ascend in a direct line with the needle-bar andspring to its oblique position again when released. Thus each descent ofthe needle through the fabric causes the presser-foot to travel forwardautomatically a predetermined distance without corresponding backwardmovement during the ascent of the needle. The play of the end K of thestirrup in the slot p causes the former before the ascent of theneedle-bar to clamp the thread J against the inner extremity of the slotp and to release the thread bc fore the descent of the needle-bar. Thusin the operation of the device as the needle descends through the fabricthe thread pays out through the eye 0 until the needle reaches itslowest position, while during the ascent of the needle-bar the thread islocked, preventing further feed of the material and causing theascending needle to withdraw part of the thread that has been carriedthrough the fabric, and thereby produce a loop of desired size on theunder side of the latter.

By adjusting the stop D to different heights on the needle-bar, asbefore explained, the lengths of loops and stitches may he gaged, asdesired, according to the flneness of the needle and thread employed.

That I claim as'iew, and desire to secure by Letters Patent, is-

l.
